6 Claims. (Cl. 299144) This invention relates to an improved shampoohead.

It is an object of this invention to provide a self-closing shampoohead.

It is still a further object of this invention to provide a shampoo headwhich may be manipulated by one hand of the user and opened and closedat will.

It is still a further object of this invention to provide a shampoo headof a self-closing type wherein a minimum of parts are required reducingcost'and increasing longevity.

It is still a further object of this invention to provide a shampoo headwherein a single element function to shut oil flow through said headwhile also preventing leakage therefrom.

Other objects and advantages will be readily apparent from the followingdescription:

The shampoo head generally designated 10 is supplied water throughflexible tube 12. Water is supplied to tube 12 from any suitable sourcesuch as a wash basin or the like or for example in place of spray nozzlein Bletcher et al. Patent No. 2,608,412 permitting regulation of thetemperature of the water While discharging through the spout outlet andthen diversion of flow through the shampoo head by opening same.

The tube 12 has a nipple 14 at its extremity which limits movement ofcollar 16 towards the extremity of the tube. The collar 16 has athreaded end 18 which screws into the rearmost extremity of housing 20wherein the valve means is housed. The foremost extremity of housing 20is provided with external threads 22 to receive the internally threadedcap 24.

The housing 20 has a chamber 26 formed therein adjacent the foremostextremity which forms a valve chamber. A resilient valve seat 28 has itsouter periphery clamped between cap 24 and housing 20 forming a gasket.This valve seat is preferably formed of rubber or similar flexible waterresistant material and has a plu rality of apertures 30 therethrough.For each aperture 30 there is provided on the foremost side of the valveseat a hollow projection 32. In this embodiment the foremost extremityof the projections 32 has three minute outlets 34 communicating with thehollow interior of the projections to more finely divide a stream ofwater flowing therethrough. These projections pass through suitableapertures 35 in cap 24.

An actuating member 36 is provided outside cap 24 having a plurality ofapertures 38 one for each projection 32. The actuating member has acentral post 40 which projects through opening 42 in cap 24 and throughUnited States Paten 2,862,766 Patented Dec. 2, 1958 central aperture 44in valve seat 28. The aperture 44 forms a snug fit with post 40preventing leakage around the post.

The post 40 at its inner extremity receives valve member 46 which isheld thereon by engagement with shoulder 48 and nut 50 which screws ontothe threaded reduced extremity of post 40.

The valve member 46 has a plurality of apertures 52 which aperturesarenot in alignment with the apertures 30 in valve seat 28. When thevalve member 46 is held against the valve seat 28 it covers apertures 30preventing flow therethrough. Likewise valve seat 28 blocks apertures 52preventing flow therethrough.

A coiled spring 54 has one extremity bearing against valve member 46 andthe other against shoulder 56 in chamber 26 which urges the valve memberinto contact with the valve seat.

The housing 20 has a plurality of ribs 58 inside chamber 26 which guidethe spring 54.

In operation water flows through tube 12 into chamber 26. When spring 54is urging valve member 46 into contact with valve seat 28, flow fromchamber 26 is shut oif. When the operator holds housing 20 in his handand depresses actuating member 36 by one or more fingers the devicetakes the position seen in Figure 3. The valve member 46 is movedrelative to the valve seat 28 permitting flow through apertures 52between the a valve member and valve seat through apertures 3t? into thehollow projections 32 and outlets 34 in the extremity thereof in amultitude of small streams suitable for shampooing.

While what hereinbeforehas been described is thepreferred embodiment ofthis invention, it is readily apparent that alterations andmodifications may be resorted to without departing from the scope ofthis invention and such alterations and modifications are intended to beincluded within the scope of the appended claims.
